Frequently asked questions
What sensors does the CIL232 mini fisheye support?
The CIL232 supports sensors up to 1/1.7\" format including the IMX728 and AR0823, resolving 12MP+ at 1.85μm pixel pitch across the 8.8mm image circle.
How wide is the CIL232 field of view?
The CIL232 provides 200° total field of view with 181° measured at the 8.8mm image circle. That is wide enough for surround-view, overhead monitoring, and multi-camera stitching applications.
Is the CIL232 weatherproof for outdoor use?
Yes. The M12A variant is IP67-rated with a sealed metal barrel and BBAR-coated front element. Both the CIL232-F1.9-M12A650 (with 650nm IRC) and CIL232-F1.9-M12ANIR (no filter) are sealed.
What lens holder works with the CIL232?
The Commonlands CLA019-LCP lens holder is the recommended mount. e-con Systems boards need an 8–13mm tall holder. Allied Vision Alvium, FLIR Blackfly S, iDS uEye XLS, TIS, and Basler Dart are also mechanically compatible.
Does the CIL232 fisheye lens ship same day from the US?
Yes. Commonlands ships all in-stock M12 lenses same day from San Diego, California for orders placed before 12 PM PST.
What is the distortion profile of the CIL232?
Under 10% F-Theta distortion. The CIL232 uses F-Theta projection rather than rectilinear — standard for fisheye lenses at this field angle. Full distortion curves including optical, F-Theta, and TV distortion are in the mechanical drawing.
